PERANGKAT KERAS KOMPUTER
"Hardware is all physical equipment used in information processing, including CPU, RAM, monitor, mouse, keyboard, printer, scanner, and others."Hardware is a communication medium that connects several networks and processes data packets so that data transmission is more effective.
(Introduction To Information System by JamesA.O'Brien dan George M.Marakas)
Dalam buku "Introduction To Information System" karya JamesA.O'Brien dan George M.Marakas di jelaskan bahwa perangkat keras komputer adalah Hardware yakni semua perlatan fisik yang digunakan dalam pemrosesan informasi, termasuk diantaranya CPU, RAM, monitor, mouse, keyboard, printer, scanner, dan lain-lain.
Perangkat Keras merupakan media komunikasi yang menghubungkan beberapa jaringan dan memproses paket data sehingga transmisi data lebih efektif.
Di kutip dari "idcloudhost.com" Hardware adalah perangkat keras dimana perangkat ini erat kaitannya dengan komputer.
Hardware atau yang lebih dikenal dengan sebutan perangkat keras adalah semua jenis komponen yang ada pada komputer yang mana bagian fisiknya dapat terlihat secara kasat mata atau dapat dirasakan secara langsung. Jadi bisa dikatakan jika hardware adalah peralatan fisik komputer yang berguna untuk melakukan proses input, proses, dan output.
Beberapa diantaranya seperti RAM, CPU, mouse, keyboard, scanner, monitor, printer, dan masih banyak lagi. Selain itu, hardware umumnya juga terlihat sebagai bentuk output dari setiap proses sistem operasi sebuah komputer. Akan tetapi untuk mendukung kerja perangkat tersebut tetap diperlukan software atau perangkat lunak tertentu. Dengan begitu setiap perintah yang diinginkan dapat beroperasi dengan baik.
Secara umum fungsi perangkat keras sebagai berikut:
- Mengelola data atau informasi
- Menerima output
- Memberi output
- Menyimpan informasi ataupun data
"Input Device is a computer unit input device that has the task of providing direct command processes by generating information in the form of digital translation to its users."
- Mouse
"A mouse is a type of hardware that functions to move the cursor on a computer screen. In addition, by using a mouse, the user will also find it easier to choose what menu he wants on the computer."
- Keyboard
"Keyboard is a type of hardware that serves to assist users in entering numbers, symbols, and letters into the computer."
- Scanner
"A scanner is a helper tool that functions to scan objects, in this case images, documents, or other things that are physical, then converted into digital form. Because it is connected to a computer, the digital object generated by the scanner will be displayed on the computer monitor."
"An output device is a type of hardware that is useful in displaying information and printing the results of data input that the user does. The data or information comes from input hardware that has passed the hardware process. For example, such as monitors, projectors, to printers."
- Monitor
"Monitor is a component that every company needs to have in doing various jobs. Generally, the work is related to documents and data."
- Printer
"A printer is an output device that is commonly used to print various kinds of text, images and documents."
- Proyektor LCD
"LCD projector is a useful hardware tool to make it easier for you to display videos and images to the LCD screen from a computer."
"A process device is a component on a computer in the form of hardware that functions to process data and process data provided by an input device which will later be displayed by the output device."
- CPU (Central Processing Unit)
"The CPU is a device that is useful in contorting all work processes on a computer. Be it from instruction, management, to producing the desired output."
- VGA (Video Graphics Array)
"VGA is a device that functions to process and process graphic data so that the results can later be displayed on a computer monitor screen."
- RAM (Random Access Memory)
"RAM is a type of hardware that can determine the speed of access in a computer."
"Storage device is a computer storage medium used to store various data such as videos, photos, digital documents and others."
- Hard disk
"A hard disk is a device that functions in storing information and data in a computer with a large enough capacity. The device has a portable-like shape."
- Flashdisk
"A pendrive is a data storage device from a computer that has a connector in the form of a USB. The connector will make it easier for this device to connect to a computer or other media used. This flash disk itself can be used to move data from one computer to another."
- Optical Disk
"Optical disk is a data storage medium that can be read or written by laser light. Generally, the optical disc here is in the form of a CD / Compact Disk or DVD / Digital Versaitle Disc."
"Peripheral devices are enhancements to connected computers to perform additional functions to make the computer work better."
